If you are using Xt, somewhere you will have made an applicationShell,
and you could add the code below to your program.  It "ticks" every
second; if you didn't like that, change the 1000 to 10000 for every
10 seconds, or 60000 for once per minute and change the sprintf()
call to use %16.16s instead ...

...

extern XtAppContext	app;

static void
_Tick(closure, id)
	XtPointer	closure;
	XtIntervalId	*id;
{
	char		*str, buf[40];
	Widget		shell;
	struct timeval	tp;
	struct timezone	tzp;

	shell = (Widget)closure;
	if (gettimeofday(&tp, &tzp) < 0)
		(void)strcpy(buf, "time = ?");
	else {
		str = ctime(&tp.tv_sec);
		(void)sprintf(buf, "%19.19s", str);
	}
	XStoreName(XtDisplay(shell), XtWindow(shell), buf);
	XtAppAddTimeOut(app, 1000, _Tick, (XtPointer)shell);
}

	...

	Widget	shell;

	shell = XtAppCreateShell(NULL, "Bart", applicationShellWidgetClass,
	    display, NULL, 0);

	XtAppAddTimeOut(app, 1000, _Tick, (XtPointer)shell);

	...
